Abstract: A generator includes a control device including a processor, and outputs electrical energy to a treatment instrument. The processor determines whether a treatment target has been heat-denatured prior to receiving an output command, and, based on determination, selects, as an operation state of the treatment instrument, one of a first mode if it is determined that the treatment target has not been heat-denatured and a second mode if it is determined that the treatment target has been heat-denatured. The processor operates the treatment instrument at the selected operation state by controlling the output of the electrical energy to the treatment instrument.

Abstract: A control device includes: a power source configured to supply a high frequency power to a treatment instrument configured to treat a living tissue; a detecting circuit configured to sequentially detect a phase difference between a voltage and a current of the high frequency power supplied to the treatment instrument; and a processor configured to control operation of the power source, the processor being configured to sequentially calculate a variation of the phase difference detected by the detecting circuit, compare the calculated variation of the phase difference with a first threshold set for a variation of a phase difference, and perform reduction processing to reduce output of the high frequency power to be supplied to the treatment instrument when it is determined that the calculated variation of the phase difference is equal to or smaller than the first threshold.
